Africa-Press – Sierra-Leone. <\/strong><\/span>Recent analysis by scientists at the University of Oxford claims the two \u201cice giants\u201d share a similar hue.<\/p>\n

British researchers have revealing new photos of Uranus.<\/p>\n

Scientists at the University of Oxford released the images of the planet and its celestial neighbor Neptune on Friday, along with analysis claiming to dispel what astronomers now believe is a common misconception about them. The research was headed by Professor Patrick Irwin at the school\u2019s Department of Physics.<\/p>\n

\u201cProfessor Irwin and his team found that both planets are in fact a similar shade of greenish blue, despite the commonly-held belief that Neptune is a deep azure,\u201d read a press release on the university\u2019s website.<\/p>\n

Widely disseminated photos and illustrations of the planets have more or less faithfully depicted the hue of Uranus according to the scientists, rendering it as a pale cyan with a very slight green tint. But Neptune has been portrayed in a shade more similar to royal blue. The researchers say artificial enhancement of photos dating to NASA\u2019s Voyager 2 flyby in the 1980s is partially to blame.<\/p>\n

Neptune is distinguished in part by its faint swirls of clouds and wind versus the more uniform appearance of Uranus. Contrast was increased on the images of Neptune to better demonstrate its texture, but the adjustments resulted in an inaccurate portrayal of the planet\u2019s color.<\/p>\n

Professor Irwin\u2019s team says single-color images captured by Voyager 2 were also sometimes incorrectly combined, creating misleading composite photos.<\/p>\n

\u201cEven though the artificially-saturated colour was known at the time amongst planetary scientists \u2013 and the images were released with captions explaining it \u2013 that distinction had become lost over time,\u201d said Irwin. \u201cApplying our model to the original data, we have been able to reconstitute the most accurate representation yet of the colour of both Neptune and Uranus.\u201d<\/p>\n

The scientists achieved similar results by applying the same process to images from various sources, which they say proves the reliability of their method.<\/p>\n

The researchers also developed an explanation for why Uranus sometimes appears to have a greener tint. High levels of methane in the planet\u2019s atmosphere typically absorb green light, but the researchers say Uranus\u2019s atmosphere is thinner around its poles for reasons they still don\u2019t understand. The planet almost spins on its side with its poles facing Earth during its summer and winter, reflecting green light towards observers.<\/p>\n

\u201cThe misperception of Neptune\u2019s colour, as well as the unusual colour changes of Uranus, have bedevilled us for decades,\u201d said Dr. Heidi Hammel of the Association of Universities for Research in Astronomy (AURA). \u201cThis comprehensive study should finally put both issues to rest.\u201d<\/p>\n
